Tianna's Comment

I agree with Alexandra about a radical being a reverse of raising a number to an exponent... This can or cannot make sense to some people... It depends on the person and their amount of skill in Math... Not saying everyone or some people are dumb.. But a lot fo the things we have learned are difficult i guess... So learning this could take a while... In the end.. im sure we will have al lthe skills we need...

Well.. yeah.. like Lanna said, this is really hard to comment on because well.. a radical's a radical and you can't really change someone's mind about what it is. Oh man.. oh yeah, and as Lanna repeated after Tianna, Chels also said that radicals could be used in science and chemistry and, well I didn't think about that until reading from your guys' posts. So thanks for the insight guys =)

It's sort of hard to respond for this one..Ya..um..Tianna said that radicals or whatever could be used in science and stuff. I don't really see why it couldn't because they're both really confusing sometimes. :) haha...i don't really know what to say for this one..All I still really know about them is that they are hard to make sense of when you don't really understand them :).

Radical. Hm. Oddly enough, I think of surfing when I hear that term. Strange.
So, as everybody else has discovered, a radical is a quantity, number, or amount, expressed as a root of another quantity. A radical can obviously be used in math, otherwise we wouldn't be blogging about it.. probably. It can also be used in Chemistry.
Example #1) : the squared root of 225 is 15 because 15x15=225. The radical is 15.. right?
Example #2) : the cubed root of.. 289 is 17! 17x17=289. What the heck? I said cubed root. I meant squared root. Geepers.

Blog Extension

This blog entry is extended till next Sunday.  That means if you have not posted I will allow you to post this week without penalty.  During the final week of school you will be required to comment on one person's post, still 50 words.  Good luck and get your stuff IN!!!

Just want to say this makes absolutely no sense to me. So I am just going on what I have googled. So a radical is a root sign. A radical is the reverse of raising a number to an exponent. The sign of a radical looks like a check mark thing. It is not on most keyboards. So it can not be shown here.

EXAMPLES

checkmarkX= -3

(checkmark X)2=(4)2
X=16

- A radical is a symbol placed over a number or an expression, called the radicand, to indicate the root of the radicand. When used without a sign or an index number, it designates the positive square root of the radicand i.e. 2. If both squares are meant, the radical is preceded ±. To indicate higher roots of the radicand. The radical sign is usually taken to indicate the principal root of the radicand, although any radicand with have (n) different nth roots. Radical is used to refer to the entire expression using radical signs and a radicand.

-examples: the square root of 16 is 4 because 4x4= 16
another example would be the square root of 56 is 8 or 7 because 7x8= 56

-A radical can be used in math and chemistry.
